super late response but I have the same problem with my name and sometimes what helps is to start with "My name is \_\_\_\_\_\_\_" or sometimes I spell it which can come across as weird because my name isn't hard to spell, or sometimes ill give my last name and then my first like "my last names \_\_\_, first name \_\_\_", or however I wanna word it that will make it easiest to say my name. its honestly so embarrassing and happens when I go out so much to the point where ive just given a different name lmao.
